ARCH.

Application filed May 26, 1924. Serial no. 716,037.

This invention relates generally. to arches used in oven construction and consists of certain novel features of construction, combination and arrangement of parts as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings:

bigure 1 is a fragmentary perspective view-ofan arch embodying my invention;

I Figure 2 is a side elevation of one of the bricks Figure 3 is a top plan view of the brick shown 1n Figure 2;

Figure 4 is an end elevation of the brick shown in Figure 2;

- Figure 5 is a view similar to Figure 1 but showmg a slightly modified form of construction;

Figure 6 is a side elevation of a modified form of brick;

Figure 7 is atop plan view of the con-v struction shown Figure 6; I

Figure 8 is an end elevation of the construction shown in Figure 6; j

Figure 9 is aside elevation of another modified form of brick;

Figure 10 is a top plan view of the brick shown in Figure 9 Figure 11 is an end elevation of the construction shown in Figures 9 and 10.

Referring now to the drawings in which like characters of reference designate corresponding parts throughout the several views, the numeral 1 designates an arch, preferably of an oven, formed of suitable fire bricks 2. As shown, these bricks are preferably rectangular shape in cross section and are arranged end to end in rows with the joints between the bricks in adjacent rows relatively staggeredand the median planes of ad jacent rows diverging upwardly. To provide a tight joint betweenv the bricks, the l-shaped channels 3 between th rows of bricks and the spaces 4 between the adjacent ends of the bricks are filled with some suitable substance such as cement.

In order that the arch may be reinforced, each brick is preferably provided with spaced transversely extending wedge-shaped siots 5. Thus, when the bricks are arranged as shown in Figure 1 of the drawings, the slots 5 are located at the top and form continuous channels throughout the width of the arch. Suitable reinforcing rods 6 eX- tend through the channels formed by the slots 5 and arete-rminally connected to the upright supporting walls (not shown) for the arch. To prevent displacement of the rods, the slots 5 are preferably filled with cement as shown at 7. This cement is preferably poured into the slots 5 when the V- shaped channels 3 and spaceski are filled, butmay, if desired, be poured into the slots 5 after the arch hasbeen installed. In any event the V -s'haped fillers in the channels 3 are connected to the wedge shapedfillers in the slotsio and cooperate therewith to keep the rods 6 in the slots 5 and thereby hold the arch together as a solidmass.

Although the fillers in the channels formed by the slots 5 in the bricks and the fillers in the intersecting V-shaped channels 3 between the rows of bricks form a strong jointof themselves, I preferably use the rods 6 as reinforcing elements. Thus, expansion and contractionwill have a much less effect on the arch. Moreover, the joints between the bricks are such that the steam or vapors from the baking chamber or the direct heat from the usual titres of the oven will not be able to escape or pass through the arch. In view of the fact the arch is formed entirely of bricks the heat 'will be distributedunifornily in the baking chamber, hence, it is "an im rovement over arches supported on steel members and the like which tend to throw flash heat in the baking chamber.

If desired, the bricks forming the arch may be arranged with the slots 5 at the bottom as shown in Figure 5 of the drawings or the bricks may be provided with other forms of slots. As shown, in Figures 6 to 8 inclusive of the drawings, the bricks 9 are provided with key hole slots 10, while in Figures 9 to 11 inclusive of the drawings, the bricks 11 are provided with rectangular shaped slots 12.

UV hat I claim as my invention is 1. An arch formed of fire bricks arranged end to end'in rows, adjacent bricks in adjoining rows being in staggered position,

a side of each of said bricks being provided with a plurality of slots, said slots having, a greater width at their inner than at their outer extremities and being aligned forming continuous "channels extending transversely of said rows, and means for reinforcing said arch comprising members extending through said channels and concrete or the like poured within said channels, the widened portion of said slots insuring the retention of said reinforcing means and said concrete Within said slot.

2. An arch formed of fire bricks, said bricks being arranged end to end. in rows extending longitudinally of said arch, said rows being arranged in an arc of a circle, each of said bricks having a plurality of slots in a side thereof, said bricks being arranged in staggered positions and having said slots aligned transversely of said rows, and reinforcing members extending through said aligned slots and retained therein by a filler of concrete or the like.

3. An arch of the class described formed of blocks arranged end to end in rows, the blocks in adjacent rOWs being in staggered elation to adjacent blocks, each of said blocks having slots in one edge adapted to be aligned to form continuous channels extending transversely of said rows, reinforcing members extending transversely of said rows and lying within said channels, a fill ing between said blocks and in said slots between said reinforcing members and the edges of said blocks, said reinforcing members and filling constituting the sole supporting means for said blocks.

at. An arch of the class described formed of blocks arranged end to end in rows, the blocks in adjacent rows being in staggeredrelation to adjacent blocks, each of said blocks having slots in one edge extending outwardly from the central portion thereof toward said edge, said slots forming continuous open channels extending transversely of said rows, metallic strips extending transversely of said rows and lying Within said channels, a filling between said blocks relatively staggered, one face of each brick being provided with a transversely extending slot, each slot being restricted at the longitudinal edges thereof, and-said slots be ing in alignment and forming a contin uous channel extending transversely of said 7 rows, a reinforcing member extending transversely of said rows and lying within said channel, and a filling in the channel formed by the slots and cooperating with the restricted portions of said slots to prevent accidental displacement of said reinforcing member from said slots.

6. An arch comprising a plurality of fire bricks of Y ranged end to end in rows, and the median planes of adjacent rows diverging upwardly one face of each brick being provided with a transversely extendingslot, theslots in said bricks being in alignment and for1ning a continuous channel extending transversely of said rows, a reinforcing member extending transversely of said rows andlying within said channel, and a filling between the blocks and in the channel, the sides of each slot forming the channel being closer together at the edgesthereol and thereby holding said filling and reinforcing member in assembled position.

In testimony whereof I aiiix my signature.
